The length would be 10yds and the width would be 5yds as they multiply together to give 50yds squared as an area and 10 is twice the amount of 5. So that means the perimeter would be 10+10+5+5 which = 30yds.
The rate of change is given as 10 per day--the number of cans the class plans to bring each day.
After 10 days at that rate, the change will be 10*10 = 100. Since the total after 10 days is 205, we compute the initial value as 205 -100 = 105. This is the number the teacher already had.
cans = 10*days +105
Answer:
218
Step-by-step explanation:
Because we need f(n) to calculate f(n+1), we have to calculate our values one step at a time. Starting with f(1) = 1,
f(2) = 5(f(1)) + 3 = 5(1) + 3 = 5+3 = 8
f(3) = 5(8) + 3 = 40 + 3 = 43
f(4) = 5(43) + 3 = 215 + 3 = 218
